This invention relates to controls and locks therefor, and particularlyto apparatus for preventing the unauthorized use or theft of an automobile.

This application is a division of my copending. application, Serial No.130,615, filed August 21, 1926.

One of the objects of the present invention is to provide a controllerwhich may be unlocked by the use of a key, but movement of thecontroller to operating position 1s prevented so long as the key remains.in the lock. Preferably, the controller includes means forautomatically moving the operating member of the controller to operatingposition when the key is withdrawn from the lock. The invention issusceptible of many appllcations, and, when applied to anelectricswitch, -the objects of the invention are accomplished byproviding an electric switch with means such as a spring tending `tomove the movable contact of the switch to closed position, a keyoperated device for releasing the spring and a Adevice which permitsunlocking the switch, but prevents complete movement of the switch toclosed position, so long as the key is in the lock. Consequently whenthe key is removed the switch will be ,automatically moved by the springto closed position.

A further object of the invention is to provide a combined switch andlock comprising separate unitary subassemblies, one of which includes anoperating member'nd lockutherefor and the other of which includes thecomplete switch. lVhen these sub-assemblies are joined together, theoperating member of the switch will be positioned for operation by theoperating member of the controller. y A furtherl object of the inventionis to providea unitary ignition coil, -ignition cir Cuit switch,controller for the switch and lock therefor including novel featuressuch yas mentioned in the foregoing paragraphs.

Further objects and advantages 'of the 4.present invention will'beapparent rom' the following description, reference being had to theaccompanyinlr drawing, wherein a .preferred form of em odiment of thepresent invention is clearly shown.

In the drawing:

Fig. 1 is a front View of a unitary lock and switch constructed inaccordance with the present invention, the rectangle drawn withdot-and-dash lines representing the instrument board to which thestructure may be attached. t

Fig. 2 is a longitudinal sectional view on the line 2 2 of Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing certain parts in positionsdiffering from the positions shown in Fig. 2.y Y Y Fig. 4 is a-sectional`view on the line 4-4 of Fig. 3.

Figs. 5 and 6 are sectional views taken respectively on the lines 5 5The. controller and lock therefor which comprises one of the unitarysub-assemblies of the structure shown in the drawing will first bedescribed. This controller includes an operating member comprising anendwise movable member 20, anda cupped disc 21 carrymg a metal stud 22surrounded by a non-conducting tube 23. As will appear more clearlyhereinafter these parts to 23 constitute the operating member oftheconltrller although the member 20 might be referredto as theoperating member, and the 'parts 22 and 23 collectively as means fortransmitting motion from the member 20. The members 2O a slidable withina tubular 24 which together with a tubular outer jacket o erating udp 21are 25 and a plate 26 provides a case and support.

for tlie operating member and' lock of the controller. The jacket 25 isprovided with an inwardlyextending flange 27' which engages a shoulder28 of the guide 24,.and with a plurality of tangs 29 which extendthrough holes 30 in the plate 26 and are `bent over so asto secure thecasing members 24, 25 and 26 in' assembled relation'. A screw. pin 31extends through the members 25 and 24 in order and 6 6 of Fig. 2.y

guide or. bearing to prevent relative rotationl between them.

Rotation between members 20 and 24 is prevented by .providing the member20 with an elongated groove 32` which receives the inner endof aiscrew33 which is threaded into a tapped hole extending through the side wallof the'member 24.

The-operatingmember 20 is locked 'coiled .around the shaft 51, one end bearing in-non-operating position shown in Fig. 2 against Ya pin 55 attached' tomember 20'and by a bolt 41 which is adapted to enter a the other bearingagainst'a side Wall 56 of recess 42 in a Side Wall 0f the member 24. thecover 52. The spring 54 is biased so as The bolt 41 is slidable within arecess 43 to tend to move the` cover 52 in a countel tion by a'spring44. The operating member. ythe movement of the cover is limite by en- 20carries a rotatable key barrel or cylinder gagementy'with the stop 55.Whenthe key 45 which can beturned only by the proper key 46 is insertedin the key operated member or indicated at 46 in Fig. 3.

This Thesub-assembly y includinl the electric key-controlled device comprisesa-movable switch for an ignition coil'wi now be destop 50 which islocated with a recess 51al proscribed. The yignition coil comprises acenvided in the right end of the operating memtral magnetizable core 60surrounded bv secber 20. The stopv 50 is attached to the ondary coil 61nd a rimary c oil 62. These squared end of the shaft 51 which extendscoils are suriinded y an external magnetic through andA is rotatably:supportedby the circuit 63 a all of these parts are housed 20. The leftend orexwithin avcontainer which comprises a metal the plunger 41operating member posed end yof the `shaft 51 4is also square and tube 64attached to non-conducting end mem-- i is attached vto a. cover. 52 forthe key hole -53 ers 65 and 66. 'The member 65 carries ter- `mai n.minals 67 and 68 connected'withithe Sends of 53 as the primary coil 62,respectively. The ter- 50 is minal 68 is connected with the outside endof of the cylinder '45. The cover 52. is tained in position covering thekey hole shown in Figs. 1 and 4 and the stop a partof the controller andlock mais? the secondary winding 61 and its inside end is connected witha terminal 69. One of the turns of the primary winding 62 is cut toprovide leads 70 and 71 which extend through hollow rivets 72 and 73,respectively, and are attached to switch contacts 74 and 75,respectively. The rivets 72 and 73 secure said contacts 74 and 75respectively, to the member 66. Member 66 is provided with a recess 76for receiving a non-conducting tube 77 having diametrlcally oppositenotches 78 and 79 for receiving, respectively, the inner ends of theswitch contacts 74 and 75. The contacts 74 and 75 "maintain the tube 77within t-he recess 76; and, since the inner ends of these contacts fitsomewhat snugly within the notches 78 and 79, rotation of the contacts74 and 75 with respect to their attaching rivets 72 and 73,respectively, is prevented.

The stationary contacts 74 and ,7 5 are adapted 'to be engaged by theoutwardly ex-l tending ilange 8() of a metallic, cup-shaped switchoperating member 81 which is located within thevtube 77. A spring 82tends to contact opera-ting member.

urge the contact operating member 81 outwardly with respect to therecess 76 and its flange 80 into engagementwith the'contacts 74 and 75.It is therefore apparent. that.'

these contacts will maintain'the contact actuator 81 within the tube 77.

The non-conducting end member-66 is supported bya metallic coil housingend member which is attached at 91 to the coil housing tube64 and whichis provided with an aperture through which'a portion of thenon-conducting member 66 extends-as shown in Figs. 2 and 6. A case or.support for'the switch is provided b the member 66 and 90 and by a.`flanged tuliularmember or collar 92 which is permanently secured to themetal coil housing tube 64. The collar 92 has an outwardly extendingflange 93 which-visv adapted to be secured to the gplate" 26 by rivets94 and rivet studs 95. Itis therefore apparent that the parts 66, 90,92and 26 will y provide a housing fortheswitch.v

Like the controller and" lock,l the ignition 'coil and switch may beconstructed as a separate sub-assembly. When ythe controllery and locksub-assembly is united to the switch subassembly, the operating memberof the c ontroller will operatively "engage the switch semblies may @bereadily disassembled by shearing olf the riveted portions in caserepairs or displacements of either sub-assembly are desired.

The studs 95 are providedwith'tapped holes 96 for receiving screws 97 bywhich' the structure may be attached instrument board'98.

The operation of the controller with respect to Vthe switch willnow beldescribed. When the controller is in locked positionas shown in Fig. 2,the switch Contact flan'ge180 lthere y breaking the circuit of the Thesesubr-asto the back .of an is se arated from the contacts 74 and 75,

rimary winding ofthe lgnition coil. Thellslnge 80 is spaced from the endwall of the -recess 76 so as to permit complete movement 'oi theoperating member- 20 to locking position While at the same time allowingfor variations in manufacture. When the key.46v.is inserted in' theJcylinder 45 and turnedto withdraw the bolt 41 from the recess 42, theoperating member 20 will be automatically moved by the spring 40into'the position shown in Fig. 3 wherein the locking bolt'41-is held inretracted position. Due to the engagement of .the stop 50 with. the wall57 defining the recess 57,` movement 1of the operatingl member 20 isarrested and hence the contact llange 80 cannot engage the switchcontacts 74 and 75 while the key remains in the lock. This featurecompels the car driver to withdraw the key from the lock in order tostart the engine of the I automobile. When this is done the stop 50 willautomatically move away from the recess 57 as already described and 'thespring 40 will be released to move the operating member2Q further towardthe left so that the spring 82 may move the contact flange 80 intoengagement with the contacts 74 and 7 5. When theoperating member 2O hascompleted its full movement toward the left, and when the' contactflange 80 has engaged the contacts 7 4 and 75 there will be a slightspace between the night hand end of the non-conductz the switch isassured although vthere may bev some slight variations inmanufacture.

'To open lthe switch the oper'ator has but to pushin theqoperatingmember 20 until the 'l `bolt 41 is "i alignment with the recess 42whereupon the spring 44' will be released'to maintaln theoperatingmember innonop erating position andthe switch in open position.' i

One ofl the principal "advantages of the present invention lis that-theopera-tor is required to remove the key from the. lock before thecontroller can, lbe moved to operating n position"`to 'render operativesome essential part of the automobile such as the ignition apparatusxAnother feature is that the controller may; b e .moved and locked in'`non-p- `erating positron or the ignition switch in" open position'withouttlie use of a key. Asa result of these.` features ,the likelihoodof a car driver leaving the key in the lock whenv nated. i Anothervfeature of the' invention is that the controller .is automatically movedto operating position 'to permit movement` of theswitch'to on position'when the key i'sref moved from thelock. No furthermanipulaytion/by.thevoperator is required to render the ignitionapparatus -operative while the form Qf embodiment of the presleavingthe-car has been. substantially elimientinvention as herein diselosed,constitutes a preferred form, it is to be understood that other formsmight be adopted, all coming within the scope of the claims whichfollow.`
